摘要

以直径12nm的气相二氧化硅(SiO₂)作为分散相,以聚乙二醇(PEG 400)作为分散介质,通过控制超声处理时间制备具有不同分散程度的剪切增稠液(STF),其中SiO₂质量分数分别为20%及25%。通过动态力学分析采用流变仪测试STF的稳态流变学性能。重点研究SiO₂分散性对STF稳态流变性能的影响。结果表明:STF的剪切增稠性能表现为黏度随着剪切速率的提高呈现先稀化后增稠的现象;随着超声处理时间的延长,气相SiO₂的分散及分布更加均匀,对临界剪切速率和峰值黏度有一定变化,进一步对临界剪切速率和峰值黏度进行优化,临界剪切速率可以达到3.49s^-1,峰值黏度可以达到1058.9Pa·s。

Abstract

SiO₂ with a diameter of 12nm was used as the dispersed phase,and used polyethylene glycol (PEG 400) as the dispersion medium.The shear thickening fluid (STF) with 20wt% and 25wt% SiO₂ mass fractions with different dispersion degrees were prepared by controlling the ultrasonic treatment time.A rheometer was used to test the steady-state rheological properties of the STF.The focus was on the influence of SiO₂ dispersion on the steady-state rheological properties of STF.The results shown that the shear thickening performance of the STF was that the viscosity became thinner first and then thickened with the increase of the shear rate.With the extension of the ultrasonic treatment time,the dispersion and distribution of gas-phase SiO₂ became more uniform,the critical shear rate and peak viscosity had a certain change,and the critical shear rate can reach 3.49s^-1 and the peak viscosity can reach 1058.9Pa·s.
